Genomic Selection (GS) has allowed the maximization of genetic gains per unit time in several annual and perennial plant species. However, no GS studies have addressed Coffea arabica, most economically important species genus Coffea. Therefore, this study aimed (i) to evaluate applicability accuracy prediction genomic estimated breeding value; (ii) estimate parameters; (iii) reduction selection cycle by Arabica coffee breeding. A total 195 individuals, belonging 13 families generation F2,...
Híbrido de Timor is the principal source for disease and pest resistance genes in C. arabica breeding program worldwide. The part of chromosome responsible introgressed from canephora to are claimed affect cup quality cultivars derived crossing Timor. Therefore, this work was done study genome introgression its impact on cultivars. For genetic relationship analysis, seventy-six accessions arabica, were analyzed using AFLP SSR molecular markers. To understand effect quality, three...
Breeding programs of the species Coffea canephora rely heavily on significant genetic variability between and within its two varietal groups (conilon robusta). The use hybrid families individuals has been less common. objectives this study were to evaluate parents from populations conilon, robusta, hybrids define best breeding selection strategies for productivity disease resistance traits. As such, 71 conilon clones, 56 robusta 20 evaluated over several years following traits: vegetative...
Genome-wide association studies (GWASs) allow for inferences about the relationships between genomic variants and phenotypic traits in natural or breeding populations. However, few have used this methodology Coffea arabica. We aimed to identify chromosomal regions with significant associations SNP markers agronomic C. a coffee panel consisting of 195 plants derived from 13 families F2 generations backcrosses crosses leaf rust-susceptible -resistant genotypes. The were phenotyped 18 genotyped...
No presente trabalho, objetivou-se avaliar a época de colheita e qualidade fisiológica sementes coentro produzidas no Norte Minas Gerais. A primeira das foi realizada aos 15 dias após o florescimento pleno, quando aproximadamente 50% plantas apresentavam flores. As demais colheitas foram realizadas 7 em dias, até as atingirem 14,0% umidade, fato que ocorreu na 6ª colheita. Imediatamente cada colheita, avaliadas quanto ao teor água, à germinação vigor (testes contagem, emergência plântulas...
Determinou-se a variabilidade genética de 37 isolados Fusarium solani e 13 oxysporum f. sp. passiflorae patogênicos ao maracujazeiro por meio do uso marcadores ISSR RAPD. Os foram obtidos maracujazeiros com sintomas murcha, encontrados nas principais regiões produtoras Norte Mineiro no município Sebastião Laranjeira – BA. Após obtenção culturas monospóricas, os tiveram seus DNAs extraídos submetidos à reação PCR. Foram selecionados nove primers primersRAPD, análise dados foi realizada,...
The genetic diversity among 46 accessions of physic nut was estimated with Nei and Li’s similarity coefficient based on a collection 69 random amplified polymorphic DNA (RAPD) sequences 37 inter-simple sequence repeat (ISSR) loci. distance between ranged from 0.13 to 0.76, an average 0.21. most divergent genotypes were 86, 71 83. A dendrogram (generated by the unweighted pair group method arithmetic mean, UPGMA) joint data matrix constructed presented only two phylogenetic groups, one which...
ABSTRACT The season of harvest is one the most important factors influencing seed quality. This study evaluated effect different harvesting times on physiological quality Coriandrum sativum L. seeds, cv. Palmeira. experimental design was completely randomized, with six treatments (harvest times) and four replications. experiment conducted during months April to October 2010. first moment seeds carried out 15 days after full bloom, when approximately 50% plants were in flowering phase. Other...
Plant breeding aims to develop cultivars with good agronomic traits through gene recombination and elite genotype selection. To support Coffea arabica programs assist parent selection, molecular characterization, genetic diversity (GD) analyses, circulating diallel studies were strategically integrated new cultivars. Molecular markers used assess the GD of 76 candidate parents verify crossing potential F 1 hybrids. Based on complementary distance, eight selected for analysis. The 12 hybrids...
Genetic diversity is essential to ensure that species maintain high adaptive evolutionary potential resist environmental stochasticity. Thus, this research aimed estimate the genetic and structure of a natural population Mauritia flexuosa its stages, using five microsatellite primers. DNA was extracted from leaves collected individuals three classes (G1-adult, G2-juvenile G3-regenerant). estimates indicated an average 7.8 alleles/locus lower observed heterozygosity (Ho) than expected (He) in...
Five hundred Nile tilapia were fed with two diets (with or without microalgae Schizochytrium sp. meal) for different periods (0, 15, 30, 45 and 60 days). The aim of the present study was to investigate effects time supply sp meat in diet on growth, fatty acid profile quality tilapia. At growth performance, only feed consumption final weight animals varied quadratically, reducing estimated period 37 38 days respectively. For characteristics fillet meat, variable b* (yellowness) showed higher...
No Brasil, muitas famílias no meio rural não têm acesso à energia elétrica, o que dificulta terem melhor qualidade de vida e desenvolvimento na propriedade rural. O sistema fotovoltaico pode ser uma alternativa conduzir a regiões rurais às quais rede convencional, geralmente, possui acesso. objetivo deste trabalho foi avaliar uso sistemas em como proposta para agropecuário aumento da vida. simulou implantação um 2,5 kWp, com armazenamento baterias, três distintas incidências radiações...
